Description
We revisit the renormalization of the Higgs mass using on-shell scheme. It is mass-dependent scheme and threshold correction is automatic. It clarifies that the renormalized Higgs mass $m^2(q^2)$ runs quadratically in the external momentum $q^2 \log q^2$ and the ratio $m^2(q^2)/q^2$ is order one up over all scale. The light Higgs mass is naturally explained by order one relation at the unification scale, without fine-tuning.
